It always amused me when I was a kid. We went fishing in Canada. The road signs and the liter gas pumps made me nuts.
Another freaky thing about Canada, from my point of view, was the use of what Americans call the ‘breakdown lane’ as a passing lane for tractor-trailers. In heavy fog or rain, unwary Yanks would pull off the road and park, only to be creamed by a hurtling semi.
